, SPARK-PRODUCING MECHANISM."

I Applieationfiled February '8, 11922. Serial no. 535,022.

To all whom it may concern."

Be it known that I, VVILLIAM-J. FRIsnIE, a citizen of the United States, a nd a resident of Chicago, in the county'ofCook and 5 State of Illinois, have invented certain new and useful Improvements in Spark-Producing Mechanism, of which the following is a specification. a

My invention relates to spark producing mechanism which is. particularly useful as an attachment on the reflectors of'miners spring which when released Will rapidly rotate the wheel in association with'pyrophoric material to produce a stream, of sparks 20 which are directed to the gas outlet .of the .lamp with which the attachment is asso-Y ciated. The wheel supporting mechanism is secured to the reflector near theouter edge thereof and the lever is attached to be swung in a diametral plane including the gas out-. let so that the produced sparks will be I thrown toward the tip to ignlte the issuinggas. The main object of my invention is to so construct the lever that when it is'rotated into position in front of the I gas outlet to wind up thespring it w-ill' form a channel a from the outlet" to the wheel which channel serves to collect issuing gas and conductv it 'in a stream between the outlet and wheel'to 35 be ignited by the sparks produced when the lever'is released. This will assure the ignition of the lamp in wind or drafts or when the pressure in the lamp is low and only a y limited amount of gas issues from the burner.

trated on the accompanying drawing on which Fig. l is a front elevational view of a. =miners, car lamp with part of the reflector- 5 broken' away and the sparking attachmenty applied thereto,

the valve lever B controlling the flow of Water to the carbide for the generation of acetylene gas. i

The sparking device comprises a frame having the base from which extends the threaded-sleeve or barrel '11 for receiving the block of pyrophoric material '12 and the spring 13,-the cap '14 having threaded engagement with the outside ofthe sleevefor acetylene lamps andis of the type in which a serrated friction wheel cooperates with pyrophoric material to produce ignition.

sparks a lever being provided for, conveniently rotating the wheel to wind upa' controlling the compression of the spring and its pressure against the pyrophoric material.

Extending upwardly from the base were thetwo parallel walls jlsfll'ldflfi whichv at opening 22 registering-with the opening 19 of the friction Wheel. The --openings re-" celve the pivot p n 17; and surrounding this pin is the coiled spring-23: which has its one end 24 secured to the "lever and its other end 25anchorcd to the-wall"15 The ,diameter of the openings 19cand 22 'is sufli cient to readily receive the coiled. spring and to permit the spring to readily after having been contracted: .7 I

When the device; isapplied to thehlamp sleevell isinserted through the hole 26 exp andin the reflector, the reflector being then clamped between the base 10 and the nut 27 engaging the threaded sleeve. The attachment is positioned with the friction wheel in Fa -diametral plane including thegas orifice ofthe tube C. The arrangement of the spring is such that the leverwill normally be held outwardly with its end against there-Hector edge; MThepyrophoric ma terial 12'is held against the friction wheel by the spring'ldand when the miner desires to light the-lamp he swings the-leverin- .,wardly toward the-lgas tube and 'thenreleases it; Swingof the lever causes the spring-.23-to be wound upqso' that uponrelease it will ra idly rotate theileverand friction wheel, th

e engagement of thesharp points on the wheel with the pyrophoric material then causing. the production of f'sparks. which are directed in a stre'am toward andacross'the gas outlet of the. tube Frequently the lamp is used where there is a draught or wind, and sometimes the sparking is weak or the pressure in the gas chamber of the lamp is low. object of this invention is to so construct the lever 21 that it will serve, when swung inwardly, to provide a passageway or channel from the gas orifice to the friction wheel whereby gas will be collected and conducted in a stream toward the friction wheel to be ignited by the sparks produced. I therefore make the lever structure of substantially U-shaped' cross sections, the walls 28 and 29 with the base 80 then forming a channel P between the gas tip and the friction wheel when the lever is swung inwardly as shown in Fig. 2. The end of the lever is widened out to form a cap 31 which will engage over the end of the gas tip when the lever is swung in, such application of the cap more or less restricting the outflow of the gas so that it will acquire some pressure particularly when the pressure in the carbide cup is below normal. The issuing gas will enter the channel formed by the lever and will travel towards the friction wheel and will be fully protected against draught. Then when the lever is released and is suddenly thrown back by its spring the produced sparks will ignite the gas stream and the flame will be communicated to the tip. Ignition of the lamp is thus assured even though the sparking on said frame and adapted to be swung to may be weak, or the gas pressure low. The wall 29 of the lever is wider than the wall 28 so that the slot 32 may be provided for accommodating the end 24 of the lever actuating spring, this end being looped around the edge of the wall 29 as clearly shown in Fig. 2.

The lever is normally held out against the edge of the reflector as indicated in Figs. 1

and 3, and the smooth rounded back of the ward and away from said outlet, said lever having a channel for receiving gas from said outlet and conducting it towards said wheel, means resisting swing of'said lever towards said outlet and tending to return it when released,- and means connecting said wheel with said lever whereby said wheel is rotated during returnof the lever to cooperate with the pyrophoric material to produce The important frame concentric'with said wheel to be swung toward and away from said outlet, said lever presenting a guldeway for the flow ofgas from said outlet towards said wheel when said lever is swung to said outlet, means for resisting swing of said lever towards said outlet and for returning it when released, and means for causing rotation ofsaid wheel during return movement of said lever whereby sparks will be generated to ignite the gas guided toward s said wheel by said lever.

In a gas lamp, the combination of a burner tip, a reflector surrounding said tip, spark producing mechanism comprising a frame mounted on said reflector, a friction wheel pivoted on said frame to rotate in the plane of the gas passageway through said tip, a lever pivoted on said frame to swing parallel with said wheel, a spring tending to swing and hold said lever outwardly away from the tip, said lever when swung inwardly bridging the space between said wheel and the tip and affording a passage way for receiving and conducting gas toward the wheel, means for rotating said wheel when the lever is returned by its spring, and pyrophoric material cooperating with the wheel to produce sparks for igniting the conducted gas.
